Examples

The following configuration file excerpt shows how to declaratively specify values for several properties of the TagMapInfo class.

<system.web>  
  <pages>  
    <tagMapping>  
      <add  
        tagType=  
          "System.Web.UI.WebControls.WebParts.WebPartManager"  
        mappedTagType=  
          "Microsoft.Sharepoint.WebPartPartManager,   
           MSPS.Web.dll, Version='2.0.0.0'"   
      />  
    </tagMapping>  
  </pages>  
</system.web>

The following code example shows how to use the TagMapCollection class to programmatically modify tag-mapping settings. This code example is part of a larger example provided for the PagesSection class.

// Get all current TagMappings in the collection.
for (int i = 0; i < pagesSection.TagMapping.Count; i++)
{
  Console.WriteLine("TagMapping {0}:", i);
  Console.WriteLine("  TagTypeName = '{0}'",
      pagesSection.TagMapping[i].TagType);
  Console.WriteLine("  MappedTagTypeName = '{0}'",
      pagesSection.TagMapping[i].MappedTagType);
}

// Add a TagMapInfo object using a constructor.
pagesSection.TagMapping.Add(
    new System.Web.Configuration.TagMapInfo(
    "MyNameSpace.MyControl", "MyNameSpace.MyOtherControl"));

' Get all current TagMappings in the collection.
Dim k As Int32
For k = 1 To pagesSection.TagMapping.Count
  Console.WriteLine("TagMapping {0}:", i)
  Console.WriteLine("  TagTypeName = '{0}'", _
   pagesSection.TagMapping(k).TagType)
  Console.WriteLine("  MappedTagTypeName = '{0}'", _
   pagesSection.TagMapping(k).MappedTagType)
Next

' Add a TagMapInfo object using a constructor.
pagesSection.TagMapping.Add( _
 New System.Web.Configuration.TagMapInfo( _
 "MyNameSpace.MyControl", "MyNameSpace.MyOtherControl"))

Remarks

The TagMapInfo class allows you to remap the types of tags at compile time. This remapping causes the mapped type to be used in place of the original tag type for all pages and controls in the ASP.NET application in the scope of the configuration file.

The TagMapCollection class allows you to programmatically access and modify the tagMapping subsection of the pages section of a configuration file. Within the tagMappings subsection, you can add and remove mappings between tag types by specifying the fully qualified strong names of the types.

Note

Unlike other attributes and collections in the pages section, tag remapping has no matching ASP.NET page directive.

Constructors

TagMapInfo(String, String)

Initializes a new instance of the TagMapInfo class based on the passed property values.

Properties

CurrentConfiguration	Gets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to. (Inherited from ConfigurationElement)
ElementInformation	Gets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement)
ElementProperty	Gets the ConfigurationElementProperty object that represents the ConfigurationElement object itself. (Inherited from ConfigurationElement)
EvaluationContext	Gets the ContextInformation object for the ConfigurationElement object. (Inherited from ConfigurationElement)
HasContext	Gets a value that indicates whether the CurrentConfiguration property is `null`. (Inherited from ConfigurationElement)
Item[ConfigurationProperty]	Gets or sets a property or attribute of this configuration element. (Inherited from ConfigurationElement)
Item[String]	Gets or sets a property, attribute, or child element of this configuration element. (Inherited from ConfigurationElement)
LockAllAttributesExcept	Gets the collection of locked attributes. (Inherited from ConfigurationElement)
LockAllElementsExcept	Gets the collection of locked elements. (Inherited from ConfigurationElement)
LockAttributes	Gets the collection of locked attributes. (Inherited from ConfigurationElement)
LockElements	Gets the collection of locked elements. (Inherited from ConfigurationElement)
LockItem	Gets or sets a value indicating whether the element is locked. (Inherited from ConfigurationElement)
MappedTagType	Gets or sets the name of the type to which the tag is remapped.
Properties	Gets the collection of properties. (Inherited from ConfigurationElement)
TagType	Gets or sets the name of the original type for the tag that is being remapped.

Methods

DeserializeElement(XmlReader, Boolean)	Reads XML from the configuration file. (Inherited from ConfigurationElement)
Equals(Object)	Compares this instance to another object.
GetHashCode()	Returns a hash value for the current instance.
GetTransformedAssemblyString(String)	Returns the transformed version of the specified assembly name. (Inherited from ConfigurationElement)
GetTransformedTypeString(String)	Returns the transformed version of the specified type name. (Inherited from ConfigurationElement)
GetType()	Gets the Type of the current instance. (Inherited from Object)
Init()	Sets the ConfigurationElement object to its initial state. (Inherited from ConfigurationElement)
InitializeDefault()	Used to initialize a default set of values for the ConfigurationElement object. (Inherited from ConfigurationElement)
IsModified()	Indicates whether this configuration element has been modified since it was last saved or loaded, when implemented in a derived class. (Inherited from ConfigurationElement)
IsReadOnly()	Gets a value indicating whether the ConfigurationElement object is read-only. (Inherited from ConfigurationElement)
ListErrors(IList)	Adds the invalid-property errors in this ConfigurationElement object, and in all subelements, to the passed list. (Inherited from ConfigurationElement)
